G2926B is a popular recipe that saw alarm during 2021 because of the difficulty in getting Ferro frit 3134. This motivated us to get a supply of the Fusion equivalent, F-12. This is a demonstration of how effective a melt fluidity test can be in comparing two glazes. Not only does the test compare the degree of melt but also surface reaction to LOI (defects), iron content and melt surface tension.
